The best idle control valve sensor replacement is the part that matches your vehicle’s year, make, model, engine, and original equipment number. Idle air control (IAC) valves regulate airflow at idle; some listings bundle an IAC valve with a throttle position sensor (TPS). The A-Premium set suits many older GM vehicles, the Toyota-listed valve targets select 1996–2000 trucks and SUVs, and the NPAUTO set is aimed at specific 1999–2002 Chevy and GMC models. Check fitment before ordering.

Idle Air Control Valve IAC And TPS
This listing combines an idle air control valve and throttle position sensor. It may suit a buyer who wants both components in one purchase rather than sourcing them separately. It is included because its product name directly matches searches for an idle control valve sensor and TPS combination.
Best for: Buyers who have confirmed their vehicle uses this specific IAC-and-TPS combination. Limitation: The supplied listing information does not identify compatible vehicles, engine sizes, or reference numbers. Verify those details with the seller or a parts catalog before choosing it.
Toyota 22270-75030 IAC Valve
This valve is listed for select Toyota 4Runner, T100, and Tacoma models with 2.4L or 2.7L engines from 1996 through 2000. Its stated reference number is 22270-75030, also written as 2227075030. Those details make it easier to compare against the vehicle’s original part.
Best for: Owners of a listed Toyota model who can confirm the year, engine, and part number. Limitation: The fitment range is specific; do not assume it fits other Toyota years or engines without checking the exact application.
Shakas IAC Valve And TPS Set
The Shakas package contains one throttle position sensor measuring 2.11 by 2.06 inches and one idle air control valve measuring 2.64 by 2.16 inches. The listing describes the IAC valve as regulating incoming air at idle and gives application examples across Buick, Cadillac, and Chevrolet models.
Best for: Buyers whose vehicle and part dimensions match the listing’s stated applications. It is selected for shoppers comparing a two-component set with specified measurements. Limitation: The compatibility list includes many model years and vehicles; confirm the precise engine and application rather than relying on the brand name alone.
A-Premium IAC Valve And TPS
A-Premium lists fitment for numerous older Chevrolet and GMC vehicles, along with selected Cadillac, Isuzu, and Oldsmobile applications. The stated examples include Silverado, S10, Sierra, Sonoma, Tahoe, and Yukon models. The listing also provides IAC reference numbers such as AC147, 17113209, and CV10011.
Best for: Owners of a listed vehicle who want a combined IAC-and-TPS listing and can cross-check the reference numbers. Its broad application details make it easier to compare than listings with no fitment information. Limitation: Broad coverage does not mean universal fit; engine and year still matter.
NPAUTO Chevy And GMC IAC Set
This combined IAC valve and throttle position sensor listing specifies select 1999–2002 Chevy and GMC applications, including Silverado, Sierra, Tahoe, Yukon, and Suburban models. It identifies 4.8L, 5.3L, 5.7L, and 6.0L engines for listed vehicles and provides interchange numbers including 217-1806, 17076327, and AC234.
Best for: Buyers whose vehicle year, model, engine, and part number align with the listing. The engine details and interchange references support a more precise check. Limitation: The listed applications vary by vehicle and year, so confirm the exact combination before ordering.
Buying Guide: How To Choose An Idle Control Valve
Is an idle control valve the same as a sensor?
Not exactly. An idle air control valve manages airflow around the throttle at idle. A throttle position sensor reports throttle position. Listings may use “idle control valve sensor” as a search phrase or bundle an IAC valve with a TPS, but these are distinct components.
How can you check vehicle fitment?
Match the model year, make, model, engine size, and—when available—the original or interchange part number. Use a vehicle parts catalog or the original component’s number to verify the application. Do not select a part based on appearance alone.
Should you buy a valve-only part or a combo?
Choose a valve-only listing when you need only the IAC valve and have confirmed it matches. A combo may suit a repair that also requires a TPS, but it does not establish that both parts are needed. Diagnose the problem before replacing components.
What details matter most when comparing listings?
- Exact fitment: Confirm year, model, and engine.
- Part number: Compare the original number with listed references.
- Package contents: Check whether the listing includes an IAC valve, TPS, or both.
- Dimensions: Use measurements as a secondary check, not a substitute for fitment data.
Frequently Asked Questions
What does an idle air control valve do?
It regulates airflow to help maintain engine idle speed under changing operating conditions.
Can a throttle position sensor replace an IAC valve?
No. They serve different functions. A TPS measures throttle position, while an IAC valve controls idle airflow.
Are IAC valves interchangeable across models from the same brand?
Not necessarily. Compatibility can depend on vehicle year, engine, and part number.
Do I need an IAC valve and TPS together?
Only if diagnosis or the required repair calls for both. A bundled listing alone does not confirm that both components need replacement.
